PostgreSQL GitHub Actions – Continuous Integration
Intro GitHub Actions (GHA) are altogether a piece of excellent machinery for continuous integration or other automated tasks on your repo.

I’ve written already a blog post “Building PostgreSQL with MSYS2 and MinGW under Windows” a year ago. But this time I want to show you two important things: cross compiling (x86, x64) using the same run-time; compiling with the latest OpenSSL support.
